I just got done building a sign like the one this guy showed how to build in SignCraft a while back. The sign interior is wood, completely covered with DiBond. It's about 3ft x 7ft x 5in. Sould the very bottom of the sign, underneath, has weep holes for moisture to escape? It's all sealed pretty good, but you know how water has a way of finding it's way inside. Here's how the inside looks,,,

Absolutely. Moisture will form from heating the interior air even if it doesn't leak. A couple of those little screens for eave vents would work great.

You may already know this. Let the dibond sides and ends protrude down past the bottom piece. This will prevent the formation of a water trap at the bottome of the sign.

Here's where I put the vents. I bought them at a hardware store. The colorc and font are the customers.

Got the idea from an aticle in Signcraft No.172. I used Lexel, bad azz sticks to everything glue. It's the same glue I use for Gemini letters.

When I worked for an electrical sign company, we made the digital reader boards over the hiway. We used a vent on the cabinets, for heat and moisture that was a one way vent. Let air out, but not in. Cabinets were all aluminum and dark painted. So it exhausted pressure from heat as well. A lot of electronics for the LED panels and thousands of LED's. Large walk in doors at the rear of the 6 foot tall by 12 to 18 feet wide cabinets were latched and sealed with weather proof tape, so there was plenty of air getting in. Common electric shop signs always have weep holes on the bottom panel. Just sayin.
